Fighting the pollinators decline in practice – Farmers’ willingness to accept an eco-scheme for their conservation in Aragon, Spain
Full text linkWe design an eco-scheme under the framework of the Common Agricultural Policy (CAP) 2023–2027 integrating the two most relevant agricultural practices for pollinator conservation: setting aside conservation land areas and reducing pesticides. Our main objectives are: (i) to measure farmers’ willingness to accept the implementation of pollinators-friendly agricultural practices, and (ii) to assess the effect of farmers’ environmental concerns and the source of recommendation on said willingness. A choice experiment is used to measure farmers’ preference for alternative designs of the eco-scheme in two cropping systems representative of the Aragonese and Mediterranean agriculture: rainfed extensive crops and irrigated/permanent crops.
As we find, Aragonese farmers are willing to uptake agricultural practices for pollinator conservation to certain extent if they are paid to do so. This is especially true for setting aside land for conservation where more demanding practices could be accepted within current Spanish unitary payments (per ha payment). The reduction or elimination of pesticides would require payments far beyond current Spanish unitary payments. Irrigated/permanent crop farmers require larger payments than rainfed crop farmers. Farmers with pro-environmental attitudes selected more environmentally-demanding alternative levels both for sparing agricultural land and reducing pesticides. Finally, the uptake of the eco-scheme could be easier if cooperatives play an active role in its promotion. The hypothetical eco-scheme presented here could be readily implemented within CAP eco-schemes while integrating the objectives of the European Pollinators Initiative, the Biodiversity Strategy 2030 and the Farm to Fork Strategy.Data collection has been funded by the EU project LIFE PollinAction (LIFE19 NAT/IT/000848).

Estratègies de lluita contra Xanthomonas spp. per a una agricultura sostenible
Full text linkEl género Xanthomonas comprende especies responsables de enfermedades como la mancha bacteriana de los frutales de hueso y el almendro, y la sarna del tomate y del pimiento, consideradas entre las más graves de estos cultivos. En este artículo se describen las enfermedades y se presentan los primeros resultados obtenidos dentro del proyecto nacional de investigación XANTHERWO.El presente trabajo se está realizando gracias al proyecto coordinado PID2021-123600OR «Modelos de Xanthomonas causantes de enfermedades en importantes en cultivos de plantas herbáceas y leñosas en España, estudios comparativos y nuevas estrategias de control (XANTHERWO)», financiado por MICIU/AEI/10.13039/501100011033/ y por FEDER, UE.Publishe
Physiological characterization of drought stress response and expression of two transcription factors and two LEA genes in three Prunus genotypes
Full text linkGlobal warming has led to a progressive decrease in rainfall, which is reflected by a reduction of water resources in the soil and a negative effect on crop production in Mediterranean areas. Under drought stress, many plants react by inducing a different series of responses at both physiological and molecular levels, allowing them to survive for a variable period of time. Therefore, in order to understand the response of roots to drought conditions, the genotypes peach x almond 'Garnem' [P. amygdalus Batsch x P. persica (L.) Batsch] and their progeny, the hybrid 'P.2175' x 'Garnem'-3 and OP -T.2175' (P. cerasifera Ehrh.) were subjected to a period of water deficit. Drought conditions with a subsequent re-watering period were tested for potted plants for one month. Stomatal conductance and leaf water potential were measured to monitor the plant physiological responses. Significant differences among the drought stress and drought stress recovery treatments and among the genotypes were observed. In addition, four genes related to the ABA biosynthesis pathway were studied for their expression by RT-qPCR: an AN20/AN1 zinc finger protein (ppa012373m); a bZIP transcription factor (ppa013046m); a dehydrin (ppa005514m) and a LEA protein (ppa008651m). Their expression profiles correlated with our physiological results of drought response, being higher in roots than in phloem tissue. In general, the expression of the four studied genes was higher after 15 days under drought conditions. Under drought and recovery conditions, the zinc finger and bZIP transcription factors showed significant differences in their relative expression levels from LEA and dehydrin. These results suggest the role of LEA and dehydrin in the regulatory response to drought stress in Prunus genotypes. Therefore, the dehydrin and the protein LEA might be potential biomarkers to select rootstocks for tolerance to drought conditions. (C) 2016 Elsevier B.V.

Effect of non-conventional atmospheres and bio-based packaging on the quality and safety of Listeria monocytogenes-inoculated fresh-cut celery (Apium graveolens L.) during storage
No full textThe increased consumption of fresh-cut celery has led to the need to explore packaging alternatives for fresh-cut celery that can meet consumer, market, and industry needs. In this study, the effect of bio-based packaging and non-conventional atmospheres on the quality and safety of chlorine-sanitized celery sticks stored at 7 degrees C was investigated. Two materials differing in permeability [a bio-based polyester (polylactic acid (PLA)) and a petroleum-based polyolefin (polypropylene/low density polyethylene (PP/PE)] and four initial gas compositions [air (A-PLA or A-PP/PE), 95 kPa O-2+ 5 kPa N-2(O-2-PLA), 99 kPa N-2 + 1 kPa O-2 (N-2-PLA), and 6 kPa O-2+ 12 kPa CO2 + 82 kPa N-2(CO2-PLA)] were evaluated. Changes in headspace composition, weight loss, surface and cut end color, texture, ethanol content, appearance, and growth of Listeria monocytogenes on inoculated celery sticks were assessed during 21 d of storage. Active MAP (CO2-PLA) out-performed passive MAP (A-PLA) in maintaining celery stick quality but not safety. Conventional active MAP (CO2-PLA) out-performed non-conventional active MAPs (O-2-PLA and N2-PLA) in maintaining celery stick quality throughout storage, but O-2-PLA suppressed L. monocytogenes growth while CO2-PLA promoted growth during the first 10 d of storage. PLA and PP/PE materials affected celery stick quality but not Listeria growth. This study shows that the initial gas composition and packaging material both impact the quality and safety of celery sticks. Overall, the combination PLA and 95 kPa O-2 proved most beneficial in maximizing both the safety and quality of celery sticks during one week of storage at 7 degrees C. (C) 2014 Elsevier B.V.
